"Chima has been evicted by the producers from the 'Big Brother' house for violating the rules," CBS said in a statement released Saturday. "She will not be part of the show's jury. Her eviction will be addressed on an upcoming broadcast of the show."
A CBS spokeswoman did not immediately return messages seeking further comment.
Simone, from West Hollywood, Calif., was last seen on the show conjuring conspiracy theories after her ally, bodybuilder Jessie Godderz, was spontaneously nominated for eviction Thursday because of the "coup d'etat," a power secretly voted on by viewers that was used to overthrow Simone's nominations.
"Looks like me and the producers need to have a little bit of a talk," she said.
Since entering the "Big Brother 11" house last month, Simone has been one of the season's most outspoken houseguests. When she was nominated for eviction during the first week, CBS censored her live last-plea speech, which referenced derogatory terms used by her competitor.
Seven contestants remain on "Big Brother 11."
